I have the exact problem above. The only variation is the model of the router and extender. But the problem is the same.
What happens is every day or two my DLINK cam is assigned a new IP address. This has no impact on the mydlink app as the cam is rock steady despite the switch. However, when this happens the cam is disconnected from my 202L. I then have to go into the 202L app and connect the cam again with the new IP address. About a day or two later, the process repeats and I have to do the same. How to fix this or am I out of luck due to a flaw with my router and extender?
